Thankfully, with the help of the government, a recycling centre was built nearby and so the rubbish littering the streets, as well as that being taken to the dump, was cut down by 60%.

dump 是名词，指"垃圾场"或"垃圾堆"，专门用来集中堆放和处理垃圾的地方。这个词也可以作动词，表示"倾倒、丢弃"的意思。 在句中 dump 作为名词使用，指代垃圾处理场所，与前面的 recycling centre（回收中心）形成对比，说明垃圾处理方式的改进。
